**ADG5412WBRUZ-REEL7: The Robust Foundation for High-Voltage Signal Routing**

In the demanding world of industrial automation, test and measurement, and communication infrastructure, the ability to reliably switch high-voltage signals is paramount. The **ADG5412WBRUZ-REEL7** from Analog Devices stands out as a premier solution, engineered to deliver exceptional performance and **unmatched robustness** in the most challenging environments. This quad, single-pole/single-throw (SPST) switch integrates advanced protection features that set a new benchmark for reliability.

At its core, the ADG5412WBRUZ-REEL7 is designed to handle a wide range of analog signals. Its capability to manage **bipolar analog signals up to ±60V** makes it incredibly versatile for applications involving high-voltage transducers, power supply monitoring, and automated test equipment (ATE) pin electronics. The device offers a low on-resistance (typically 80 Ω) and ensures minimal distortion, preserving signal integrity across the entire signal path.

The most critical feature of this switch is its integrated **±60V fault protection on the source and drain pins**. This is a game-changer for systems exposed to voltage transients, accidental shorts, or other fault conditions. In the event of a power supply sequence failure or an overvoltage event—for instance, if a system power supply is absent while analog signals are still present—the device actively clamps the fault current and survives. This inherent protection **eliminates the need for complex external protection circuits**, saving board space, reducing component count, and significantly enhancing system-level reliability.

Further bolstering its durability is its **latch-up proof construction**. Utilizing a proprietary silicon-on-insulator (SOI) process technology, the ADG5412WBRUZ-REEL7 is immune to the latch-up phenomena that can plague conventional CMOS devices when subjected to high-current or overvoltage stresses. This SOI foundation ensures deterministic operation and prevents catastrophic failure, even when the absolute maximum ratings are exceeded.

Complementing these features is its **enhanced ESD performance**. With ESD protection rated at ±4 kV (Human Body Model) on the switch pins, the device offers superior handling robustness, drastically reducing yield losses during manufacturing and field failures during the product's lifespan. This makes it an excellent choice for applications where equipment is frequently connected and disconnected.

Housed in a compact 16-lead TSSOP package, the ADG5412WBRUZ-REEL7 provides a high level of integration and performance in a minimal footprint. Its combination of high-voltage switching, built-in fault protection, latch-up immunity, and ESD resilience makes it an indispensable component for designers building systems that cannot afford to fail.

**ICGOODFIND:** The ADG5412WBRUZ-REEL7 is a robust, fully-protected quad SPST switch that provides a critical safeguard for high-voltage systems. Its integrated **±60V fault protection**, **latch-up immunity** from SOI technology, and **enhanced ESD ratings** offer unparalleled reliability, simplifying design and ensuring long-term operational integrity in harsh industrial and instrumentation environments.
